The Red Devils snapped up the Colombian star from Monaco on a season-long loan deal from Monaco on transfer deadline day.

United have the option to sign Falcao permanently next summer but despite the attention surrounding the deal, a member of staff at the club shop appears to have spelt out his six-letter surname name wrong on the replica top.

Old Trafford fans will be hoping Falcao, not Flacao, takes to the pitch this weekend against QPR.

He took part in Colombia's 1-0 friendly defeat to Brazil at the weekend and has joined in with training at Carrington ahead of his Premier League debut.

The striker has played down concerns over his fitness insisting he feels in great shape.

He said: "I'm so happy to be back and to have this opportunity life has granted me after the injury.

"Physically I feel spectacular. I have been able to play without any kind of trouble whatever.

"Throughout my rehab people have given me so much support and sent me so many kind messages."
